when player right-click ob this block. tileEntity save one Item from HeldItem

and block must refresh render for show getting item.

 

but redraw not working and when disconnect from world item not saved.(if break block then item dropped correctly)

 

what i need to do for save data and refresh render block?

 

If I understand your problem correctly, I've had this exact problem before, too. My issue was that the entity's tracking range (specified in EntityRegistry.registerModEntity) wasn't big enough; changing it to a large value like 80 fixed it -- this means that players 80 blocks away will receive updates. In SP, it will just pause updating if the player leaves that range.

Did you register your TileEntity? To make the client work correctly, you will need to send packets (TileEntities have a description packet, you can use that).

Of course! I forgot to register!

can't understend.

constructor TileEntity call two time

and created two with different id

public class BlockAdvertising extends Block implements ITileEntityProvider 
{
...
@Override
public TileEntity createNewTileEntity(World p_149915_1_, int p_149915_2_) {
	// TODO Auto-generated method stub
    	TileEntityAdvertising tileentity = new TileEntityAdvertising();
         return tileentity;
}

 

when call method: tileentity return with first id

public boolean onBlockActivated(World p_149727_1_, int p_149727_2_, int p_149727_3_, int p_149727_4_, EntityPlayer p_149727_5_, int p_149727_6_, float p_149727_7_, float p_149727_8_, float p_149727_9_)
    {
        if (p_149727_1_.isRemote)
        {
            return true;
            
        }
        else
        {
        	TileEntityAdvertising tileentity = (TileEntityAdvertising)p_149727_1_.getTileEntity(p_149727_2_, p_149727_3_, p_149727_4_);

 

when call render method, return tileentity with second id

 

public class AdvertisingRenderer implements ISimpleBlockRenderingHandler {
....
@Override
public boolean renderWorldBlock(IBlockAccess world, int x, int y, int z,
		Block block, int modelId, RenderBlocks renderer) 
{
	// TODO Auto-generated method stub
TileEntityAdvertising ent = (TileEntityAdvertising)world.getTileEntity(x, y, z);

 

 

 

The constructor is called twice, ones for the server and ones for the client. That's why you need to sync the two, as the server and the client both have different copies of the TileEntity which can contain different values than the TileEntity on the other side.

Thanks, working!

I'm add:

worldObj.markBlockForUpdate(xCoord, yCoord, zCoord);

in method: MarkDirty() and onDataPacket()

worldObj.markBlockForUpdate(xCoord, yCoord, zCoord);

That updates the block, not any entities.
